i have a 2017 6.4 RAM 2500. It cools well but there seems to be very little heat when you push the temp up. Truck has 106600 milesdoesnt matter if you turn the fan up it still gives very little heat. even if you go into the 80's it still blows vry little heat.. Temp gauge is right about the middle of the gauge. the engine and the antifreeze are both hot (normal). could it be air in the line ? dealer replaced the oveerflow bottle and something under the intake. ideas?
